The liquefied natural gas (LNG) value chain represents $4 to $8 billion dollars of investment from start to finish. It begins with natural gas extracted from underground reservoirs and is sent through a pipeline to a liquefaction facility.

At the liquefaction facility, impurities are removed from the gas, and it is sent through three cooling processes until it reaches a final temperature of minus 260 degrees Fahrenheit.

The chilled gas, now LNG, is then loaded onto specially designed tanker ships where it will be kept chilled for the duration of the voyage, which may last anywhere from four to thirty days, depending on the destination port.

Once the ship arrives at a regasification terminal, the LNG is offloaded into large storage tanks, built with full-containment walls and systems to keep the LNG cold until it is turned back into a gaseous state.

When the LNG has been warmed back to its natural state, the gas is moved into pipelines which will deliver the natural gas to consumers, power plants and industrial customers across the country.
